Fundamentals of a new class of oxidation processes based on thermal and photo-catalysis in basic zeolites (TPC.6057)

Project nummer: tpc6057

Omschrijving van het onderzoek

An efficient catalytic conversion from hydrocarbons to molecules that contain oxygen (oxygenates) has been since long a 'dream' reaction. For instance, alkanes that only have a net heating value could be converted to more functionalized molecules with a significant added value for application in chemical products and materials. Unfortunately, in practice a direct selective conversion is still not possible. During the nineties is was discovered that the desired reactions could be accomplished at low temperatures, even at ambient temperature, in Ca-modified zeolites. Oxygen and alkanes are probably activated by the electric field of the Ca2+ ions. However, the problem was that the resulting oxygenate is strongly adsorbed next to the Ca-ion and is unable leave the catalytic site. The aim of the research is to better understand how the Ca-zeolite catalyst functions, and on the basis of this information to find a solution for the problem of the removal of the products from the catalyst.
